VALVE APPARATUS 'David D. Goldberg, Springfield, and Aaron R. Kligman, Indian Orchard, Mass., assignors to The Automatic Cone Valve Company, Indian Orchard, Mass., a corporation of Illinois Original No. 2,054,812, dated September 22, 1936, Serial No. 30,054, July 6, 1935.

" 15 Claims. (Cl. 251-97) member is reciprocable in abodybetween seated or wedged and non-seated positions and is rotatable between open and closed positions all to the end that the said plug may be wedged or seated in the body in an open, closed or intero drawings wherein mediate throttling position. The seating of the plug provides a tight metal to metal contact of the plug and body thereby to seal the plug and prevent fiuidpassing therearound which is likely to cause sticking of the plug, corrosion of the parts and other inju ious effects.

As one special fea ure of the improved structure the plug is journalled or pivoted in the body at its upper and lower ends by means of journals which are relatively small in diameter in comparison to the diameter of the plug. Not only do the relatively small diameters facilitate free movements of the plug with a minimum of. friction and operating effort but the plug is accurate-- ly guided in its reciprocating and rotative move -ments. This obviates a dragging tendency of the plug in the body such as would be broughtabout by unbalanced pressure at opposite sides of the plug tending to move the plug from its true axis of movement, all to the end that the co-acting seating parts of the plug and body are protected against injury and are at all times capable of providing a tightly sealed relation in all positions of the plug. 7

Another feature of the invention is the provision of means for reciprocating the plug betweenwedged orseated and non-seated positions and for rotating the plug between'open and closed positions while in non-seated position. The said means is not only characterized by its simplicity and efliciency but is arranged to releasably lock the plug in a seated position.

Various other novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the preferred form of the invention, reference being had to the accompanying Fig. 1 is a sectional elevational'view through a valve embodying the novel features of the invention; I

Referring now to the drawings more in detail the invention will be fully described, it being understood that various changes and modifications may be made in the form of the valve without departing from the spirit and scope of theinvention.

A valve body is represented at 2 having ports indicated at 4 and this body while it is shown as being of the flanged type may be of screw or bellend type or be otherwise constructed for connecting the same to a pipe line. v

A plug 6 is provided in the body which is preferably conical and it has as a special novel feature a lower journal or pivot part 8 that is mounted for rotation and reciprocation in a suitable hub or journal It]. A stem or spindle l2 which has its lower end fixed to theplug and as usual the plug a has a passageway or opening 1 therethrough which is adapted to register with the ports of the body when in an open position. p

A cap I is fixed to the upper side of the body and it has a transverse wall l6 and a bearing part I B in which the stem I2 is mounted for reciprocation and rotation. A gland 20 is provided in connection with the bearing l8, as shown to provide a stufl'ing box for the stem and spindle and thereby properly seal the same but yet permit its rotation and reciprocation.

A yoke 22 is supported by and secured to the cap I4 and this has a sleeve 24 rotatable therein and adjustable up and down relative thereto. The sleeve is threaded adjacent its upper end and at its lower end andcollars such as 26 are in threaded engagement therewith so that the sleeve may be moved up and down to various positions of adjustment and locked in place by the said collars 26.

The upper end of the stem or spindle I2 is reciprocable in the sleeve 24. By particular ref erence to Fig. 5 it will be noted that the upper extremity ll of the stem is flattened oil, at its 25 of the sleeve 24 at opposite sides of the stem to provide substantially horizontally disposed shoulders 30 (see Figs. 2 and 5).

A lever L has lower cheek parts 32 which are spaced apart and these are disposed adjacent the flattened sides of the upper end of the stem (see Figs. 1 and 5). The lever L is pivoted to the upper end of the stem as by a pin 34 which extends through the cheeks of the lever and extremity of the stem I3. This is so the lever L may swing on the stem while at the same time it functions to rotate the stem and thereby the plug all as will hereinafter appear.

Stops 3B and 38 extend between the cheeks of the lever which are adapted to abut the upper surfaces 30 of the ledges 28 associated with the upper end of the sleeve 24. i

Links 40 are pivotally connected at their lower ends to the upper end of the sleeve as by bolts 42 and their upper ends are pivotally connected to the lever L as at 44. A projection 48 extends from one side of the lever L to facilitate swinging of the said lever and this may be relatively short so that a handle in the form of a pipe H may be slipped thereover to provide leverage. It will be obvious that the projection may extend from any side of the lever depending upon' the particular requirements.

A stop member 50 having a downwardly de-* pending part 52 1s carried by the head 25 of the sleeve 24. The part 52 is adapted to abut the yoke 22 at 54 thereby to limit the swinging movements of the lever L and associated parts so that the plug 6 may be positioned in a full open or closed position.

'As has been explained the plug and its stem are reciprocable and rotatable so that the plug may be elevated from a seated position shown in Fig. 1 to an unseated position and then rotated to another position such as its open or intermediate position and then reseated in this latter position.

Figs. 1 and 3 show the position of the lever L with plug in its closed, seated position. To move the plug to an open position, the lever L is rotated counterclockwise from the position shown in Fig. 3 so that it assumes the position shown in Fig. 2. This initial swinging of the lever causes the upper pivotal connection of the links and lever L to pass counterclockwise through the vertical axis of the stem or to the left thereof whereby the stem is elevated to elevate and move the plug from its seated relation in the body.

When the lever has been moved to a nonseated position of the plug the stop 36 abuts the upper side of the part 28 of the sleeve to prevent the further swinging of the levers counterclockwise while the spindle and plug are free for rotation tolocate the plug in full open or at some intermediate throttling position. With the plug in full open position the stop part 52 bring up against one of the stops 54 on the yo e.

After the plug has been moved to an open position it is desired to reseat or wedge the plug in said position. This is accomplishedby swinging the lever L clockwise from the position shown in Fig. 2 so that the pivotal connection between the links 40 and lever L swings towards and slightly past the vertical axis of the stem whereupon the stop 38 abuts the upper side of the part28. This pin 38 is so arranged relative to the part which it abuts that the pivotal connection 44 passes just slightly beyond the vertical 20,978 sides. Ledges 28 extend upwardly from a head axis of the stem whereby the plug is forced downwardly by the stem and is releasably locked by a toggle action in a seated orwedged position.

The form of the invention shown in Figs. 6 to 8 inclusive, will now be described in detail.

A body 60 has a tubular member 62 at its upper side which may be held in place by a member 64 in screw-threaded engagement with the body. A plug 56 has a part 61 at its lower end suitably journalled in the body and a stem 68 at its upper side is reciprocable and rotatable in the part 62.

Theupper end of the' part 62 is threaded, as shown, and a cap nut 10 and gland 12 provide a means for packing the stem as is usual in valve structures.

A collar block 14 is rotatable on the part 62 and it is held against movement upwardly by a collar 16. A stop pin 18 on the lower end of the plug is arranged to abut ribs such as in the body to limit swinging movements of the plug to its full open or closed positions.

A lever L has separated parts 82 at its upper end which are pivoted as by pin 84 to the upper end of the stem. Links 86 have their lower ends pivoted on eccentrically disposed parts 88 of pivot pins 90 associated with blocks 14 and their upper ends are pivotally connected at 94 to the cheeks B2 of the lever. Stop pins 96 and 98 extend between the checks of the lever and are adapted to abut the sides of the stem to limit the movement of the lever L. i

As with the form of the invention previously described, the plug is elevated from seated or wedged position, rotated and then reseated again. For instance, from the closed seated position shown in Fig. 6, the plug is elevated to non-seated position by swinging lever L counterclockwise and then the lever is rotated to rotate the stem and plugto position the plug in a full open or an intermediate position. When the plug is positioned as desired it is reseated by swinging the lever clockwise. Also, as in the former case, when the lever swings to the plug seating position as in. Fig. '7, the pivotal connection associated with the upper ends of the links and levers passes across the vertical axis of the stem and slightly beyond so that the links and the pivotal connections with the lever, stem and associated parts operate with a toggle action to releasably lock the lever and thereby the plug in its seated or wedged position.

In order that the plug may be tightly wedged or seated in the body in its wedged position the pins 90 may be rotated to vary the position of their eccentric parts thus raising and lowering the pivotal axis of the lower ends of the links 88.

Having described the novel valve structure it will be appreciated that various changes and modifications may be made in the form thereof without departing from the spirit and scope of the invention.
